Dude, that's a beautiful home gym. Much respect!!
I like going to my local gym. It used to be a Powerhouse gym, and I think they stopped paying the license fees, but still has good equipment, etc. It has great lighting... LOL I always look twice as big and ripped there than I do at home. Yeah, I'm vain. I usually train between 7:30-9:30am so the truly big guys aren't there, just us retirees and stay-at-home moms.
Now that it's summer, I've been seeing HS and college age boys working out. I know it's stupid, but I can't fully explain just how much satisfaction I get lifting about half the weight these kids are "trying" to throw around while being 3X their size. If they learn just one thing this summer, maybe it's that slow, controlled movement and squeezing at peak contraction stimulates the muscle a whole lot more than whatever it is that they're doing.
